Comparison of Some Preconditioners for the Incompressible Navier-Stokes Equations
Published online by Cambridge University Press: 24 May 2016
Abstract
In this paper we explore the performance of the SIMPLER, augmented Lagrangian, ‘grad-div’ preconditioners and their new variants for the two-by-two block systems arising in the incompressible Navier-Stokes equations. The lid-driven cavity and flow over a finite flat plate are chosen as the benchmark problems. For each problem the Reynolds number varies from a low to the limiting number for a laminar flow.
